Title: Normal paraffin adsorptive separation using non-normal hydrocarbon pre-pulse stream
Inventor: KULPRATHIPANJA SANTI
IPC: B01D53/02
Filed: 1991-01-31
Abstract: An adsorptive separation process for separating normal paraffins from non-normal hydrocarbons wherein the paraffins have from about 10 to about 35 carbon atoms per molecule, using a molecular sieve adsorbent having an effective channel diameter of about 5 angstroms is improved by passing a non-normal hydrocarbon input stream into the adsorption zone at adsorption conditions to promote the selective adsorption of the straight chain hydrocarbon constituents of the feed material in contact with the adsorbent in preference to the lighter straight chain hydrocarbon constituents of the desorbent material also in contact with adsorbent.

Title: Bulk explosive charger
Inventor: BAUMGARTNER OTTO F
IPC: F42D1/10
Filed: 1991-06-11
Abstract: ABSTRACT         There is disclosed, according to the present invention, an apparatus and method for loading explosives, exhibiting little water resistance, into water filled blast holes without contamination of the explosives by water.  A pressure charger vessel, capable of being filled with bulk explosives of low density and low water resistance, such as ammonium nitrate fuel oil, is connected to a flexible plastic sleeve.  A pneumatic plug fixedly connects the lower portion of the pressure charger vessel to the plastic sleeve.  The plastic sleeve is lowered into a blast hole by means of a weight.  Compressed air is then introduced into the pressure charger vessel and a valve means located between the sleeve and the pressure charger vessel is opened, permitting pressurized ammonium nitrate fuel oil to be pushed downwardly into the flexible plastic sleeve.  Projections and recesses on the outer surface of the plastic sleeve facilitate the expulsion of water from the blast hole.

Patent CA-2050956-A1 (CA)
Inventor: FOSTER JOHN P
IPC: C22C16/00
Filed: 1991-09-09
Abstract: This invention is for the processing of a somewhat broader range of compositions, including ZIRLO material. It controls creep rate in an alloy having, by weight percent, 0.5-2.0 niobium, 0.7-1.5 tin, 0.07-0.28 of at least one of iron, nickel and chromium and up to 220 ppm carbon, and the balance essentially zirconium. The method is of a type which utilizes subjecting the material to a post extrusion anneal, a series of intermediate area reductions and intermediate recrystallization anneals, with one of the intermediate recrystallization anneals possibly being a late stage beta-quench, a final pass area reduction, and a final stress relief anneal. The creep rate is controlled to about the desired amount per hour by the use of an average intermediate recrystallization annealing temperature and a final pass area reduction combination selected from the designated area of a designated figure, with the figure being selected based on whether the post extrusion anneal was an alpha or a beta anneal; on whether the final anneal was a stress relief anneal or a recrystallization anneal, and whether or not a late stage beta-quench was utilized, and the desired creep rate range. The method may also comprise subjecting the material to an alpha post extrusion anneal and a final stress relief anneal, and controlling the creep rate by the use of certain intermediate recrystallization annealing temperatures and final pass true area reductions.

Patent CA-2063199-A1 (CA)
IPC: A61D3/00
Filed: 1992-03-17
Abstract: Abstract An animal headgate has a rectangular frame in which a pair of neck-engaging yokes is mounted for coordinated sliding move-ment between a fully open position and a fully closed position. A parallelogram linkage interconnects each yoke to an associated sleeve on the rectangular frame so that movement of the sleeve between an upper and a lower position will move the yokes between the fully open and the fully closed position, respectively.  An over-center spring arrangement urges the yokes from a neutral, open position toward the fully closed position.  A unidirectional locking mechanism associated with each of the posts permits the spring arrangements to close the yokes about the neck of an ani-mal but prevents unassisted opening of the yokes thereby restraining the animal.  A notched bar and associated catch mounted on the upper end portions of the yokes provide for auto-matic operation of the headgate,  The spring arrangements act to hold the notched bar in the catch at a preselected open position for the yokes.  Opening pressure on the yokes from the shoulders of an animal that has inserted its head through the yokes will release the notched bar and permit the spring arrangement to move the yokes to engage the neck of the animal.

Abstract: Un appareil de calcul de la position et de l'azimut d'un véhicule pour corriger à la fois une erreur personnelle et une erreur d'azimut découlant de l'accumulation d'une erreur de capteur et d'une erreur de cartographie, et pour obtenir à la fois une précision de position élevée et une précision d'azimut élévée. Pour cela, l'appareil de calcul de la position et de l'azimut du véhicule fonctionne de manière à déterminer une vitesse angulaire et une distance de déplacement pour le véhicule, à calculer une position et un azimut à bord du véhicule, et à détecter une condition de déplacement rectiligne du véhicule. Enuite, après l'obtention des mesures GPS des positions durant le parcourt rectiligne du véhicule, on établit des droites de régression en reliant les longitudes et latitudes des position mesurées durant le parcourt rectiligne du véhicule à la distance de déplacement à partir de l'origine du véhicule. La position d'un véhicule et son azimut sont calculés à partir des droites de régression durant le parcourt rectiligne du véhicule, puis une position et un azimut à bord du véhicule, calculés à partir des valeurs détectées comme  vitesse angulaire du véhicule et  distance de déplacement, sont modifiés en se rapportant à la position et à l'azimut déduits des mesures du GPS.

Abstract: ABSTRACT A backlash reduction mechanism for incorporation into a selectively latchable vehicle seat hinge assembly for reducing the backlash between a plurality of interconnecting movably operative latch members positioned seriatim with respect to one another in the vehicle seat hinge assembly and method for producing the mechanism are disclosed. The latch members are retained in interposed relation between first and second hinge plates.

The eccentrically operative rotatably adjustable backlash reduction means is for achieving selective adjustment of the relative positioning of one or more of the latch members to one another, wherein, when eccentrically operative rotatably adjustable backlash reduction means is rotated about the first pivot axis, it interacts with the latch member mounted thereon such that latch member is axially moved generally toward the next latch member positioned seriatim therewith, thereby to cause selective reduction in the amount of backlash between these two latch members and subsequently between other juxtaposed ones of the latch members.
